Abstract

Abstract Summary

Overview

The study focuses on the electromagnetic exposure a passenger experiences within a pure electric vehicle, specifically from the inverter's electromagnetic fields.

Methodology

Utilizing the principles of electromagnetic dosimetry, an electromagnetic model that includes a pure electric vehicle's body, an adult human body, and the inverter was developed.

• The model used the finite element method to calculate magnetic induction intensity (|B|), induced electric field intensity (|E|), and induced current density (|J|).
• Assessments were focused on the human trunk and central nervous system of both the driver and the front seat passenger.

Findings

Numerical results from the study show that the electromagnetic fields are well below the safety exposure limits as defined by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

Conclusion

The exposure levels inside the vehicle, due to both DC and AC bus currents of the inverter, are deemed safe according to international standards.
